    Simple Jfet Buffer SMD Version "In-a-Box" Looking for Some Tips...

    Hey Folks, So I bought a few Simple Jfet Buffer SMD version PCBs, and I wanted to mess around with putting one into the tiniest possible Hammond enclosure and making just a basic little utility pedal for use in troubleshooting or wherever it's needed in someones signal chain. This represents a...

    Your Valhalla Has Weird Holes.

    Hey @Robert so there are all these unmarked pads on the Valhalla PCB, and they're not listed or mentioned on the build doc either, so I'm not sure what to do. PCB photo with "mystery pads" circled and numbered is at the bottom of this post, referred to number-by-number in the following: These...

    SOLVED Does slowly building noise indicate a specific failing component?

    Hey guys, so… I have this Golden Falk that I built, and it sounds great…FRIGHTENLY like a real Plexi…but it has this funny specific issue: It sounds perfect for about seven minutes of play through, and then this random crackling noise starts slowly entering the sonic landscape….first very...

    Why Does My Space Heater Only Like NOS RCA Tubes?

    Okay @vigilante398 and everyone else, I need to preface this post by pointing out that I am posting build pics for you guys to examine (I know it's the first thing requested for troubleshooting, always) but you guys are going to find them to be an absolutely crazy-looking jumbled, inexplicable...

    SOLVED SMD J201s: Help Me Not F@$k This Up…

    So I’m making the Golden Falk, and I unexpectedly ran out of traditional J201s as I was getting started. BUT I happened to have a bunch of the @PedalPCB SMD ones that I haven’t tried yet…okay! So, can you guys take a look at the placement of the J201 on the right in the photo below (I have NOT...

    Golden Falk Build Doc Cap Specs - Typo?

    Nevermind…the build specs say ceramic for everything, but then the appropriate ones DO say film right next door in notes. Semitypo. Can’t figure out how to delete posts on mobile, derp. @Robert you can zap this post.

    SOLVED Simple Jfet Buffer - Mega-Dumbass Wiring Question...

    Okay so it IS a very simple circuit...but here is where I am a dumbass: I'm building this as a separate circuit, in a separate enclosure...it's not permanently piggybacking onto another pedal. SO, I see the pads for power (+) and (-), and one pad each for input/output. But what about the...

    What’s the Deal with Pedalpcb Film Cap Sizing?

    I feel like I should know this already, 2 years into this obsession… On most pedalpcb build documentation—or even if not, it can be inferred by the size of the component outline silkscreened onto the actual PCB—there is indication of whether one should use a 7mm x 2mm film cap, or the bigger...

    6-Band EQ—“Metal-as-F&@k” Version!

    So I’ve been messing around with these EQ calculators… http://www.muzique.com/lab/gyrator.htm http://www.muzique.com/schem/filter.htm …and using it to swap out caps/resistors on the 6-band EQ. I socketed all the relevant pads to test my work before I “made it real” and to my utter...

    Replacing "Six Pads" Jacks with "Two Pads" Jacks On a PCB...

    Okay this might sound like dummy talk because I don't know the proper terminology so bear with me... So you guys know how all of the PCBs that are sold by pedalpcb.com use the typical old-school 1/4" mono jacks for inputs/outputs that require only two leads—"positive" and "ground", right? Well...

    Replacing a momentary footswitch with a toggle...

    Hey Crew, So I have this fancy programmable analog EQ stomp box (Free the Tone PA-10G) that has a soft-touch 3PDT foot switch that allows one to toggle between four different user presets. And likewise on the other side of the pedal for on/bypass duties. I'm about to re-house this sucker...

    Minor Beef with Cepheid chorus LED brightness on LFO…

    Hey folks so I finished a Cephid build that is pretty flawless, but I do think the brightness of the LFO LED is really weak. Pretty hard to even see in a lit room. Is there a different kind of LED that I should be utilizing for the LFO, or alternately could I swap out the relevant resistor...

    Looking for subjective opinions on chorus pedal sounds…

    So I just finished the Cephid chorus pedal, and it sounds great, but it’s not QUITE what I’m looking to put in my rig. The Cephid (BOSS CE-1/2) sound I am now realizing has that thick, warm 70s/early 80s vibe that’s kinda “always on” and even at its most conservative setting verges on a...

    Thumb Sucker - What Did I “FRY”?!?

    Hey folks, So I had a Thumb Sucker build that was complete and sounded perfect, but THEN… I started desoldering/resoldering pots and jacks because I wanted to reposotion them…now the ratio control is non-functional…possibly from overheating components in the chain whilst desoldering, otherwise...

    Cepheid Chorus: help me find legit 3207/3102 chips!

    Hey folks, So after finishing a ridiculously clean and meticulous build of the Cepheid with every component tested before being soldered in, I am clearly having the EXACT same symptims and problems as this fellow here…...

    Integral Preamp - Modifying the EQ bands?

    Hey Folks, So I just finished this fun-and-easy-build, and it sounds great, but it got me thinking about messing around with what frequencies the "bass" and "treble" knobs actually affect. So much so, that I socketed some of the resistors and capacitors that I THINK are responsible for tonal...

    Modifying Old Rockman Pedal for "Always On"...?...

    Hey folks, So if any of you recognize me and my posts from the last couple years, you my know that "my deal" has usually been figuring out ways to house pedalpcb stuff into rack-mountable enclosures. Any pedal I love goes into my rack alongside its' peers in a big rack enclosure, and is...

    Help Me Wire Up a (one-switch) TRIPLE Pedal!

    Hey folks! So I took it upon myself to build and wire up a THREE CIRCUIT stomp box—Dwarven Hammer boost, End All Red overdrive, Muzzle gate—into a really large Hammond enclosure. I wanted it to be a single-switch pedal, so that all three circuits were "always-on", or completely off at the...

    Can I Use Electrolytics or Tantalum Caps in Place of Film Caps?

    Probably a silly newb question, but I ask because of film caps having no polarity versus the tantalum or electrilytics having a positive and negative lead. Is it doable?

    Changing the Frequencies of the 6-Band EQ..

    Hey so I am hoping to start building the 6-band EQ (potentiometer version) very soon, but would like to change the frequency center on each pot to something different than the stock kit. I just KNOW that I’ve seen a thread about how to do it on this forum, but for the life of me I can’t find it...
